WORKING VALVE.

Application led February 12, 192.3. Serial No. 618,611.

To @ZZ whom t may concern:

Be it known that we, VINCENT P. KILL, a citizen of the United States,residing at Lawton, in the county of Comanche, in the State of Oklahoma,and ORRIN J GAs'rnR, a citizen of the United States, residing atAnadarko, in the county of Caddo, in the State of Oklahoma, haveinvented certain new and useful Improvements in Working Valves, of whichthe following is a specification7 reference being had to theaccompanying drawings.

This invention relates to improvements in working valves and moreparticularly to working valves forpump plungers utilized in the pumpingof oil or water from wells.

An important object of the invention is to provide in a device of thischaracter a positively seating valve the parts of which are soconstructed that the device is relatively long lived and will operateunder yadverse conditions, such as when encountering paraiiine, sand orheavy gas pressures.

A further object of the invention is to provide a valve of the type inwhich the valve stem is directly connected with the pump plunger to beoperated thereby to seatv and unseat the valve.

A still further object of the invention is to provide in a device ofthis character a construction whereby both the valve and valve seat arereversible and double ended so that they may be interchangeablyemployed, thereby doubling `the normal life thereo Other objects andadvantages of the invention will appear in the course of the followingdescription.

In the accompanying drawin wherein for the purpose of illustration isshown a preferred embodiment of our invention and wherein like referencecharacters designate like parts throughout: Y

Figure 1 is a side elevation of a valve constructed in'accordance withour invention;

Figure 2 is a longitudinal sectional view therethrough; land l Fi ure 3is a transverse sectional view on the line 3-3 of Figure 1.

Referring now more particularly to the drawings, the numeral indicates apump barrel within which is operativelyv mounted a plunger rod 11directly connected at its lower end with a valve rod or stem 12. The

'valve-rod or stem 12 is threaded at its upper end, as shown at 13, orconnection with the pump plunger rod 1and for the reception of limitingand lock nuts 14 and 15 respectively. The lower end of the stem 12 isthreaded, as indicated at 16, for engagement with a member 17 providedupon its ends with ground faces 18, forming the member 17 as a doubleended valve. The member 17 is reversible upon the threads 16 and at itsupper end abuts against guide vanes 19 formed upon the stem 12 andalfordug therebetween fluid passages or grooves'20.

Mounted about the stem 12 is a plunger barrels 21 of greater diameterthan the stem 12 and which is provided at its upper end with an enlargedhead 22 producing a downwardly directed shoulder 23 for a purposehereinafter described. The lower end of the barrel 21 is eXteriorlyscrew-threaded, as indicated at 24, for engagement by a ring member 25for maintaining in position about the barrel a plurality of cup leathers26 and spacers 27, which cup leathers lact in the usual manner to sealthe space between the working barrel 10 and the plunger barrel 21. Thering 25 when in fully applied position has its lower end spaced from thelower end of the plunger barrel 21 so as to permit engagement with thevplunger barrel of the upper end of the sleeve 28. The sleeve 28 isformed at each end thereof with a valve seat 29 for coaction with one ofthe ground faces 18 of the member 17 and is interiorly constructedintermediate its threaded end portions, as at 30, to form a slide forthe outer faces of the vanes 19. The lower vend l of the ring 25 isshaped, as at 31, to conform to the valve seat 29 which is arrangeduppermost so as to form a tight joint at this point and to protect thevalve seat which is not in use from corrosion or abrasion. The valveseat which is arranged lowermost will, of course, be intermittentlyengaged by the uppermost ground face 18 of the lmember 17 during thereciprocation of the stein 12. ln order to protect the lower face 18 ofthe member 17, l provide a washer disk 32 of approximately the samediameter as the member 17 and which is maintained in position by aretaining screw 33 directed through the washer disk and engaging in thelower end of the stem 12. This disk prevents direct contact of articleswithin the working barrel/with the face 18 and iurthermore serves as aretainer to prevent accidental disengagement oi the member 17 from thelower end of the stem.

In the operation of the device, when the plunger rod is moveddownwardly, the

, member 17 is separated from the sleeve 28,

the' stem 12 moving downwardly until the limiting nut engages the upperend of the head 12. At this time the valve will be' 15 12 will cause theupper ground face 18 to come into engagement with the lower end ofsleeve 28, the valve seat 29 of the sleeve 28 closing the lower endofthe plunger barrel and retaining above the valve all liquid which haspreviously passed therethrough. Upon a seat of the valve becomindamaged, the valve may be removed an -the sleeve' 28 inverted. It thevalve face 18 itself be damaged, the member 17 is inverted, in eitherevent a new structure being provided by the inversion.

It will be obvious that by the structure hereinbefore set forth we havenot only provided a working valve having a pair of interchangeable seatsand valves, but in this provision have provided means for locking theretaining element or sleeve 25 in position and likewise means forIprotecting the seats and valve faces which are not in use. It willfurthermore be obvious that the structure hereinbefore set forth iscapable of some change and modilication without materially departingfrom the spirit of my invention and we accordingly do not limitourselves to such Specific structure except as hereinafter claimed.

What we claim is v1. In a working valve, a hollow-valve barrel, packingelements `carried by the barrel, a ring having threaded engagement withthe lower end of the barrel and maintaining said packing in positionupon the barrel, a sleeve likewise having threaded engagement with thebarrel, locking said ring in adjusted position thereon, said sleevebeing provided upon opposite ends thereof with valve seats and beingreversible in its engagement with the barrel, a stem extending throughthe barrel bore and capable of limited longitudinal reeiprocationtherein, and a member carried by the lower end of the stem having aground face seating on the seat at the lower end of the sleeve when thesame ,l said packing in position upon the barrel, a sleeve likewisehaving threaded engagement maratea with the barrel locking said ring inadjusted position thereon, saidfsleeve being provided upon opposite endsthereof with valve seats and being reversible in its engagement with thebarrel, ak stem extending through the barrel bore and capable of limitedlongitudinal reciprocation therein, and a member carried by the lowerend of the stem having a ground lface seating on the seat at the lowerend of the sleeve when the same is at the upper limit of its travel,said ring having the lower face thereof formed to conform to the valveseat at the upper end of said ksleeve to thereby pro tect the same.

3. In a working valve, a hollow valve barrel, packing elements carriedby the barrel, a ring having threaded engagement with the lower endofthe barrel andmaintaining said packin in position upon the barrel, aSleeve likewlse having threaded engagement with the barrel locking saidring in adjusted position thereon, said sleeve being provided upon thelower end thereofl with a valve seat, a stem extending through thebarrel bore and capable of limited longitudinal reciprocation therein,and a member carried by the lower end of the stem and reversible thereonhaving a ground face formed at opposite ends thereof, the uppermostground face of the member seating on the Seat at the lower end of thesleeve when the stem it at the upper limit of its travel, and meansengaged with the lower end of the stem maintaining said .member` inposition upon the stem and protecting the ground face at the lower endthereof.

4. A working valve, a hollow valve barrel, packing elements carried bythe barrel, a ring having threaded engagement with the lower end of thebarrel and -maintainng said packin in position upon the barrel, a sleevelikewise having threaded engagement with the barrel locking said ring inadjusted position thereon, said sleevebeing reversible 1n its engagementwith the barrel and being provided upon opposite ends thereof l`withvalve seats, a lstem extending through the barrel bore and capable oflimited longitudinal reciprocation therein, and a member reversiblycarried by the lower end of the stem having at opposite ends thereofground faces, the uppermost ground face of the member seating on theseat at the lower end of the sleeve when the stem is at the upper limitof its travel.
